A1Z26 Cipher

An A1Z26 cipher (also known as a Number Cipher), is a simple substitution cipher. It is made by replacing each letter with its numbered position in the alphabet. For example, A is replaced with the number 1, B with 2, etc. .

To encode - that is, to convert the plaintext message into ciphertext - take the letters of your message from the top row (plaintext) and replace them with the numbers of the bottom (ciphertext).

Using an A1Z26 cipher, the following: "What does a house wear? Address." would look like this:

"23 8 1 20 4 15 5 19 1 8 15 21 19 5 23 5 1 18? 1 4 4 18 5 19 19."
